Atucci17 Posted June 14, 2017 Report Posted June 14, 2017 Having problems midrange power I have it bored 40 over, v-force reeds, pro circuit exhausts. Can't get it tuned right what should the jet setting be and the needle?? Quote
Schweet97Z Posted June 15, 2017 Report Posted June 15, 2017 What's your location? Do you know your elevation?Sent from my iPhone using Tapatalk Quote
ginger Posted June 15, 2017 Report Posted June 15, 2017 midrange can be the needle, im going to assume you checked for air leaks? Quote

ginger Posted June 15, 2017 Report Posted June 15, 2017 by air leaks, meaning the motor could be sucking air, check that your carb boots arent riped. that intake gaskets are good, ever base gaskets, or pressure test it. there is a thread on how to do that with simple home depot stuff. Quote
Schweet97Z Posted June 15, 2017 Report Posted June 15, 2017 360 is big for a stock bike with pipes. 27.5 pilot. Needles on middle clip. 270-310 I'd say for your main but you will need to play with thatSent from my iPhone using Tapatalk Quote
gusto Posted June 15, 2017 Report Posted June 15, 2017 What VF reed? If its a 4 try a 30 pilot. Is it stroked? 360 main sounds big for a stock stroke unless its really ported up. Quote

Also when trying to hit the powerband while driving it backfires. Do you guys think it's the CDI?? Tested the coil and its fine I'm maybe thinking it's that? Quote
gusto Posted June 21, 2017 Report Posted June 21, 2017 Definitely could be the cdi. So it was running better with the other jet? It might be jetting then. You need to check out how to make a leak down tester and do that first. Quote
ginger Posted June 21, 2017 Report Posted June 21, 2017 i have heard of being to lean causing backfiring. quick question, how clean is your air filter. I had midrange issues at one point because i had an outerwear go bad, and it was like putting a bag over the air cleaner. Quote
